The Before route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). Configure for High Availability. To clear the routes cache, make a POST request to /actuator/gateway/refresh. The following example configures an AddResponseHeader GatewayFilter that uses a variable: The Spring Cloud CircuitBreaker GatewayFilter factory uses the Spring Cloud CircuitBreaker APIs to wrap Gateway routes in It can be used as API gateway in microservice architecture and supports dynamic routing and filtering functions. For more detailed examples of how to use any of the following filters, take a look at the. The following example configures such a fallback: The following listing does the same thing in Java: This example forwards to the /inCaseofFailureUseThis URI when the circuit breaker fallback is called. Fork 3. The Spring Cloud CircuitBreaker filter can also accept an optional fallbackUri parameter. This filter works only with HTTP (including HTTPS) requests. The following example configures an AddRequestParameter GatewayFilter that uses a variable: The AddResponseHeader GatewayFilter Factory takes a name and value parameter. Spring Cloud Gateway matches routes as part of the Spring WebFlux HandlerMapping infrastructure. To write a custom global filter, you must implement GlobalFilter interface as a bean. Configuring Predicates and Filters For, 15.4. AddResponseHeader is aware of URI variables used to match a path or host. It requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. If the fallback is called, the request is forwarded to the controller matched by the URI. Displays information about a particular route. Setting this value to zero blocks all requests. This paper will introduce its usage in detail. Sign in Spring Cloud Gateway, or SCG for short, is a sub-project from the Spring Cloud family that provides an API gateway built on top of a reactive web stack. How does it work? The Gateway is defined with a number of routes, each with Predicates to match the request to the route. Add a response header named X-Request-Foo with a value of Bar to the original response. The following listing configures a RewritePath GatewayFilter: For a request path of /red/blue, this sets the path to /blue before making the downstream request. The RemoveHopByHop Headers Filter removes headers from forwarded requests. The maxSize parameter is the maximum data size allowed by the request header (including key and value). Easy to extend and/or customize using standard Spring patterns @ryanjbaxter thanks, the core code is a filter https://github.com/spring-cloud/spring-cloud-gateway/files/3244970/code.txt ,but it can't modify header in a post filter,is it a right way writing like this? The stripVersionMode parameter has the following possible values: NEVER_STRIP, AS_IN_REQUEST (default), and ALWAYS_STRIP. response Header Transformations: . exceptions: A list of thrown exceptions that should be retried. Spring Cloud Gateway aims to provide a simple, yet effective way to route to APIs and provide cross cutting concerns to them such as: security, monitoring/metrics, and resiliency. Writing Custom Route Predicate Factories, 17.2. Spring Cloud has it's own way of defining Feign clients, it's done with Spring MVC annotations. Likewise to the RedisRateLimiter Filter Factory it requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. The resulting response is similar to the following: The response contains the details of all the routes defined in the gateway. It is the name of the header to be removed. You can read more about them in the. To retrieve the routes defined in the gateway, make a GET request to /actuator/gateway/routes. The Header route predicate factory takes two parameters, the header and a regexp (which is a Java regular expression). The gateway maintains a client pool that it uses to route to backends. There are convenience methods that you can use to mark an exchange as routed By default, it creates a NettyChannel by using the default TrustManagerFactory. Various properties can be specified inside your application.properties file, inside your application.yml file, or as command line switches. or check if an exchange has already been routed. The RemoveJsonAttributesResponseBody GatewayFilter factory takes a collection of attribute names to search for, an optional last parameter from the list can be a boolean to remove the attributes just at root level (thats the default value if not present at the end of the parameter configuration, false) or recursively (true). {githubmaster}/src/main/java/org/springframework/cloud/gateway/security/TokenRelayGatewayFilterFactory.java[filter] To enable this kind of repository, the following property has to set to true: spring.cloud.gateway.redis-route-definition-repository.enabled If youre using load-balanced routes, you need to explicitly define your. backoff: The configured exponential backoff for the retries. The FallbackHeaders factory lets you add Spring Cloud CircuitBreaker execution exception details in the headers of a request forwarded to a fallbackUri in an external application, as in the following scenario: In this example, after an execution exception occurs while running the circuit breaker, the request is forwarded to the fallback endpoint or handler in an application running on localhost:9994. The body is cached in a request attribute defined by. The global CORS configuration is a map of URL patterns to Spring Framework CorsConfiguration. The Forwarded Headers Filter creates a Forwarded header to send to the downstream service. The following listing configures a SetStatus GatewayFilter: In either case, the HTTP status of the response is set to 401. The JSONToGRPCFilter GatewayFilter Factory converts a JSON payload to a gRPC request. The resulting response is similar to the following: The response contains the details of the global filters that are in place. This filter takes an optional keyResolver parameter and parameters specific to the rate limiter (described later in this section). Well occasionally send you account related emails. httpStatusCode: The HTTP Status of the request returned to the client. If the response is already cached and a new request is performed with no-cache value in Cache-Control header, it returns a bodiless response with 304 (Not Modified). Spring Cloud Gateway requires the Netty runtime provided by Spring Boot and Spring Webflux. The XForwarded Headers Filter creates various X-Forwarded-* headers to send to the downstream service. The RewritePath GatewayFilter factory takes a path regexp parameter and a replacement parameter. Typically, there will be a name key and an args key. The url parameter should be a valid URL. The following two examples are equivalent: When the request size is greater than the permissible limit, the RequestSize GatewayFilter factory can restrict a request from reaching the downstream service. If the URI has a scheme prefix, such as lb:ws://serviceid, the lb scheme is stripped from the URI and placed in the ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR for use later in the filter chain. Embed. The following example shows how to do so: The SetPath GatewayFilter factory takes a path template parameter. A utility method (called get) is available to make access to these variables easier. If the URL has a lb scheme (such as lb://myservice), it uses the Spring Cloud ReactorLoadBalancer to resolve the name (myservice in this example) to an actual host and port and replaces the URI in the same attribute. Temporary bursts can be allowed by setting burstCapacity higher than replenishRate. The following listing configures a filter chain: To enable gateway metrics, add spring-boot-starter-actuator as a project dependency. As a result, you can inject request headers and query parameters, for instance, and you can constrain the incoming requests with declarations in the mapping annotation. It uses the Spring WebSocket infrastructure to forward the websocket request downstream. responseCode; responseHeaderTransformations; responseMessage; type; . This is the full configuration of the shortcut configuration of the Cookie predicate shown above. The following example configures CORS: In the preceding example, CORS requests are allowed from requests that originate from docs.spring.io for all GET requested paths. Options. It is a Spring Boot application with Spring Cloud stuff that can make it sit between clients and their requests and multiple services, where it offers features such as predicates for shaping. Predicate: This is a Java 8 Function Predicate. Usually it's a common requirement that applications can . The following listing defines a set of default filters: The GlobalFilter interface has the same signature as GatewayFilter. This is the number of tokens taken from the bucket for each request and defaults to 1. Spring Cloud CircuitBreaker supports multiple libraries that can be used with Spring Cloud Gateway. The following listing configures a Retry GatewayFilter: A simplified "shortcut" notation can be added with a single status and method. The RemoveRequestParameter GatewayFilter factory takes a name parameter. The following listing configures a SetResponseHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. You must use $\ to mean $ because of the YAML specification. The following listing configures a redis-rate-limiter: Rate limits below 1 request/s are accomplished by setting replenishRate to the wanted number of requests, requestedTokens to the timespan in seconds, and burstCapacity to the product of replenishRate and requestedTokens. If none of these parameters are configured but the global filter is enabled, by default, it configures 5 minutes of time to live for the cached response. Naming Custom Filters And References In Configuration, 18. The following headers (shown with their default values) are added: Strict-Transport-Security (max-age=631138519), Content-Security-Policy (default-src 'self' https:; font-src 'self' https: data:; img-src 'self' https: data:; object-src 'none'; script-src https:; style-src 'self' https: 'unsafe-inline)'. It should be available as a GitHub (or similar) project or attached to this issue as a zip file. Passing headers with Spring Cloud Feign. For the external controller/handler scenario, headers can be added with exception details. status: The HTTP status of the request returned to the client. To configure per-route timeouts: AddRequestHeader is aware of the URI variables used to match a path or host. If You Appreciate This, You Can Consider: We are thankful for your never ending support. The following example shows how to do so: You can route gateway routes to both HTTP and HTTPS backends. The RequestRateLimiter GatewayFilter factory uses a RateLimiter implementation to determine if the current request is allowed to proceed. If two hops of trusted infrastructure are required before Spring Cloud Gateway is accessible, then a value of 2 should be used. URI variables may be used in the value and are expanded at runtime. methods: The HTTP methods that should be retried, represented by using org.springframework.http.HttpMethod. Policy to specify how to modify the response code, body and headers. We've already covered its basic usage in earlier tutorials, so we won't get into those aspects here. This is similar to how AddRequestHeader works, but unlike AddRequestHeader it will do it only if the header is not already there. .route("test1", r -> { This combined filter chain is sorted by the org.springframework.core.Ordered interface, which you can set by implementing the getOrder() method. The primary scenario is to use the fallbackUri to define an internal controller or handler within the gateway application. During your stay, take advantage of some of the amenities offered, including a 24 hour front desk, room service, and a gift shop. The following listing configures a RedirectTo GatewayFilter: This will send a status 302 with a Location:https://acme.org header to perform a redirect. application.yml. The resulting response is similar to the following: The response contains the details of the GatewayFilter factories applied to any particular route. URI variables may be used in the value and will be expanded at runtime. All pre filter logic is executed. You can enable, disable, or configure policies to control how they modify APIcast. The j_spring_security_switch_user function in Cisco Unified Intelligence Center (CUIC) 8.5.4 through 9.1(1), as used in Unified Contact Center Express 10.0(1) through 11.0(1), allows remote attackers to create user accounts by visiting an unspecified web page, aka Bug IDs CSCuy75027 and CSCuy81653. The following listing shows how to cache the request body GatewayFilter: CacheRequestBody extracts the request body and converts it to a body class (such as java.lang.String, defined in the preceding example). it is proxying. If the Gateway Handler Mapping determines that a request matches a route, it is sent to the Gateway Web Handler. The Path Route Predicate Factory takes two parameters: a list of Spring PathMatcher patterns and an optional flag called matchTrailingSlash (defaults to true). Sharing Routes between multiple Gateway instances, 17.1. This predicate extracts the URI template variables (such as sub, defined in the preceding example) as a map of names and values and places it in the ServerWebExchange.getAttributes() with a key defined in ServerWebExchangeUtils.URI_TEMPLATE_VARIABLES_ATTRIBUTE. There is an abstract class called AbstractRoutePredicateFactory which you can extend. Getting the refreshTokenMono is webclient call which is in a different service.. By the time it gives the response, main response is already about to commit and wont allow us to modify the response headers. If it is not, a status of HTTP 429 - Too Many Requests (by default) is returned. The collection of filters applied to the route. This could be useful for maintenance windows. To use the ProxyExchange, include the right module in your classpath (either spring-cloud-gateway-mvc or spring-cloud-gateway-webflux). It creates a new named header (toHeader), and the value is extracted out of an existing named header (fromHeader) from the incoming http request. The header is added to the response if configured with the following property: The StripPrefix GatewayFilter factory takes one parameter, parts. Multiple matching segments are allowed. I got the root cause. This is the value of the Location header. The following example configures a before route predicate: This route matches any request made before Jan 20, 2017 17:42 Mountain Time (Denver). import static org.springframework.cloud.gateway.support.RouteMetadataUtils.RESPONSE_TIMEOUT_ATTR; @Bean outcome: The outcome, as classified by HttpStatus.Series. If so, the same rules apply. also note that the gist doesn't take the decoders into account from upstream like here. method: Method name in the service that handles the request. This section details how to retrieve route filters, including: To retrieve the global filters applied to all routes, make a GET request to /actuator/gateway/globalfilters. the request should only be allowed if it comes from a trusted list of IP addresses used by those This type of Repository is not suited to populate Routes across multiple Gateway instances. ServerWebExchangeUtils.setAlreadyRouted takes a ServerWebExchange object and marks it as routed. The Method Route Predicate Factory takes a methods argument which is one or more parameters: the HTTP methods to match. The Cookie route predicate factory takes two parameters, the cookie name and a regexp (which is a Java regular expression). The following example configures a KeyResolver in Java: This defines a request rate limit of 10 per user. Removes an existing route from the gateway. This handler runs the request through a filter chain that is specific to the request. This strips the service ID from the path before the request is sent downstream. For more information on circuit breakers and the gateway see the Spring Cloud CircuitBreaker Factory section. If the URL has a forward scheme (such as forward:///localendpoint), it uses the Spring DispatcherHandler to handle the request. Displays the list of routes defined in the gateway. Retrieving the Routes Defined in the Gateway, 15.5. The following listing configures a RequestSize GatewayFilter: The RequestSize GatewayFilter factory sets the response status as 413 Payload Too Large with an additional header errorMessage when the request is rejected due to size. The following listing configures a SetRequestHostHeader GatewayFilter: The SetRequestHostHeader GatewayFilter factory replaces the value of the host header with example.org. The KeyResolver is a simple one that gets the user request parameter Add a Header for the original response, configuration example: spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org filters: - AddResponseHeader=X-Response-Foo, Bar. This predicates matches the Host header that matches the pattern. The following example configures a DedupeResponseHeader GatewayFilter: This removes duplicate values of Access-Control-Allow-Credentials and Access-Control-Allow-Origin response headers in cases when both the gateway CORS logic and the downstream logic add them. Appending multiple headers can be controlled by the following boolean properties (defaults to true): spring.cloud.gateway.x-forwarded.for-append, spring.cloud.gateway.x-forwarded.host-append, spring.cloud.gateway.x-forwarded.port-append, spring.cloud.gateway.x-forwarded.proto-append, spring.cloud.gateway.x-forwarded.prefix-append. It provides a convenient method to apply a transformation to JSON body content by deleting attributes from it. Otherwise, the original value in the client request is sent. It supports basic downstream HTTP exchanges through methods that mirror the HTTP verbs. When communicating over HTTPS, the client initiates a TLS handshake. .application.yml. The following example below is invalid: The Redis implementation is based on work done at Stripe. The following two examples are equivalent: For some usages of the gateway, properties are adequate, but some production use cases benefit from loading configuration from an external source, such as a database. 25Modify Response Body GatewayFilter Factory; By default, if the KeyResolver does not find a key, requests are denied. It uses the Netty HttpClient to make the downstream proxy request. The following example shows such an errorMessage: There are certain situation when the host header may need to be overridden. For a full working sample see this project. You can add headers to the downstream response by using the header() methods on ProxyExchange. The following listing configures a StripPrefix GatewayFilter: When a request is made through the gateway to /name/blue/red, the request made to nameservice looks like nameservice/red. Spring Cloud Gateway || Modify Response Body Using Post Global Filter modify response body of route in spring cloud gateway Hi everyone, have you ever worked with Filters ? All. privacy statement. The redis-rate-limiter.requestedTokens property is how many tokens a request costs. 2016-10-05: 4.3: CVE-2016-6426 CISCO Here is a link to someone asking about ordered filters that may provide more insight: #1341. SetResponseHeader is aware of URI variables used to match a path or host. The following example configures a RewriteResponseHeader GatewayFilter: For a header value of /42?user=ford&password=omg!what&flag=true, it is set to /42?user=ford&password=***&flag=true after making the downstream request. keyResolver is a bean that implements the KeyResolver interface. The routine of modifying the response body with Spring Cloud Gateway is the same as the previous request body; Configure routing and filters through code; . The following listing configures a RequestHeaderSize GatewayFilter: This will send a status 431 if size of any request header is greater than 1000 Bytes. The first step is to create a ServerHttpResponseDecorator object and override the writeWith method. The following example shows how to achieve the same configuration with Java: The Weight route predicate factory takes two arguments: group and weight (an int). The following listing shows the KeyResolver interface: The KeyResolver interface lets pluggable strategies derive the key for limiting requests. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. The response is put in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute for use in a . Retrieving Information about a Particular Route, 15.6. Modify request body. The parts parameter indicates the number of parts in the path to strip from the request before sending it downstream. Easy to extend and/or customize using standard Spring patterns Raw. Fully expanded arguments appear more like standard yaml configuration with name/value pairs. The following properties are available: To disable the default values set the spring.cloud.gateway.filter.secure-headers.disable property with comma-separated values. HttpHeadersFilters are applied to the requests before sending them downstream, such as in the NettyRoutingFilter. Modifying the Way Remote Addresses Are Resolved, 5.12. Value 3.9. None of the prior documentation applies to what follows. When setting the This filter adds a timer metric named spring.cloud.gateway.requests with the following tags: routeUri: The URI to which the API is routed. spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org predicates: - Host: {segment}.myhost.org filters: - AddResponseHeader=foo,bar-{segment} The default implementation of KeyResolver is the PrincipalNameKeyResolver, which retrieves the Principal from the ServerWebExchange and calls Principal.getName(). You can configure the logging system to have a separate access log file. Spring Cloud supports Resilience4J out of the box. This predicate matches with a header that has the given name whose value matches the regular expression. In the next tutorial of Spring Cloud Gateway Example we will implement these theories and build an application with microservice architecture using Spring Cloud Gateway and demonstrate working examples on web filters to modify request and response body. as the separator. The preceding route matches if the request contained a red query parameter whose value matched the gree. The SecureHeaders GatewayFilter factory adds a number of headers to the response, per the recommendation made in this blog post. The following example configures an AddRequestParameter GatewayFilter: This will add red=blue to the downstream requests query string for all matching requests. returned from the route it wraps. The default filter is a rewrite path filter with the regex /serviceId/?(?
. Note that the $ should be replaced with $\ because of the YAML specification. Spring Cloud Gateway can forward OAuth2 access tokens downstream to the services Once matched, the Gateway executes pre-request logic on each of the filters applied to the route. pass the authentication token downstream to the services (in this case The following describes an alternative style gateway. If max-age is present on the original response, the value is rewritten with the number of seconds set in the timeToLive configuration parameter. Currently, only forward: schemed URIs are supported. When a request is made through the gateway to /json/hello, the request is transformed by using the definition provided in hello.proto, sent to com.example.grpcserver.hello.HelloService/hello, and the response back is transformed to JSON. Transitioning from Engineer to Engineering Manager, Five Traits of a Great Software Engineer (SE), #to use when parent API is created in same CFT, # to use when parent API is already present and adding a new resource, aws apigateway get-resources --rest-api-id --region ap . In Puma (RubyGem) before 4.3.3 and 3.12.4, if an application using Puma allows untrusted input in an early-hints header, an attacker can use a carriage return character to end the header and inject malicious content, such as additional headers or an entirely new response body. However, you can also reroute the request to a controller or handler in an external application, as follows: In this example, there is no fallback endpoint or handler in the gateway application. essentially skipping the filter. With MVC, it also supports forwarding to a local handler through the forward() method. This is the rate at which the token bucket is filled. This filter also automatically calculates the. The route configuration allows applying CORS directly to a route as metadata with key cors. Route filters allow the modification of the incoming HTTP request or outgoing HTTP response in some manner. The following example configures a weight route predicate: This route would forward ~80% of traffic to weighthigh.org and ~20% of traffic to weighlow.org. This property takes a list of filters. In configuration, you can reference the bean by name using SpEL. I think i have to go for a blocking call here. The following listing configures a ReactiveLoadBalancerClientFilter: If there is a Route object in the ServerWebExchangeUtils.GATEWAY_ROUTE_ATTR exchange attribute, the RouteToRequestUrlFilter runs. To allow for simple configuration in Java, the RouteLocatorBuilder bean includes a fluent API. It must be a Java System Property, not a Spring Boot property. Each item defines the name and the arguments of a given predicate. You can configure these timeouts can be configured (defaults shown) as follows: Configuration for Spring Cloud Gateway is driven by a collection of RouteDefinitionLocator instances. Shortcut configuration is recognized by the filter name, followed by an equals sign (=), followed by argument values separated by commas (,). For relative redirects, you should use uri: no://op as the uri of your route definition. Body is cached in a request costs the Spring DispatcherHandler to handle request.
